Thanks Terry for starting this interesting thread. QS8s were on the top of my list for surrounds but according to that review Axiom’s QS8s may be a problem if the rear speakers are placed within a foot of the rear wall. So if space from the wall is an issue, do other experts here recommend using M2s for surrounds rather than QS8s? Since I'm still reviewing my options I'd appreciate all your thoughts regarding wall space and using QS8s or not.
